Abstract:
Bearing assemblies, apparatuses, systems, and methods include bearing assemblies where one of the bearing assemblies may include angled bearing surfaces having a planar shape.
Abstract:
Embodiments of the invention relate to bearing assemblies and associated cardiopulmonary bypass blood pumps in which the bearing assembly includes a stator and a rotor each including bearing surfaces oriented so as to be generally opposed to one another. The bearing surface may comprise a polycrystalline diamond material including a plurality of bonded diamond grains defining a plurality of interstitial regions therebetween, in which a non-metallic catalyst (e.g., a carbonate) and/or at least one derivative thereof is disposed interstitially between the bonded diamond grains.
Abstract:
Embodiments of the invention are directed to compact bearing assemblies configured to operate in small spaces and/or in harsh environments, bearing apparatuses including such bearing assemblies, and method of operating such bearing assemblies and apparatuses. For instance, one or more compact bearing assemblies may at least partially rotatably secure a shaft of a power generation unit to a housing thereof. Also, a first compact bearing assembly may connect or couple to the shaft and may rotatably engage a second compact bearing assembly, which may be connected or otherwise secured to the housing.

Abstract:
A bearing assembly includes a support ring circumferentially surrounding a central bearing axis and a plurality of superhard bearing elements coupled to the support ring. Each of the plurality of superhard bearing elements has a base, a superhard bearing surface, and a lateral periphery extending between the base and the superhard bearing surface. The superhard bearing surface has a partial-ellipsoidal surface shape. A bearing apparatus includes an inner bearing assembly and an outer bearing assembly. A subterranean drilling system includes an output shaft operably coupled to a bearing apparatus.

A subterranean drilling system may include a drill string and a rotary drill bit coupled to the drill string. The rotary drill bit may include a bit body and a cutting element coupled to the bit body, with the cutting element being structured to rotate in response to torque applied to the cutting element. The system also may include a cam assembly coupled to the drill string, a cam follower assembly in contact with a cam surface of the cam assembly, and a torque-applying structure coupled to the cam follower assembly. The torque-applying structure may be configured to apply torque to the cutting element in response to relative rotation between the cam assembly and the cam follower assembly.
